ORA-19035: Invalid select item of the query in newContextFromHierarchy()

当尝试在给定的“Hierarchy”上下文上创建新的上下文,并且该Hierarchy中存在无效的查询项(SELECT)时,就可能引发ORA-19035: Invalid select item of the query in newContextFromHierarchy() 错误。
场景一:
当查询的SELECT子句的个数不是1时,就可能会抛出ORA-19035: Invalid select item of the query in newContextFromHierarchy() 错误。例如:
SELECT * FROM test;
将会引发ORA-19035: Invalid select item of the query in newContextFromHierarchy() 错误。
场景二:
当查询的SELECT子句返回字段类型与Hierarchy上下文中要求的字段类型不匹配时,就可能会抛出ORA-19035: Invalid select item of the query in newContextFromHierarchy() 错误。
1、确保SELECT子句的个数符合Hierarchy上下文的要求:
正确的查询格式如下:
SELECT FROM
